"Expanding the Lactococcal Cell Wall Polysaccharide Paradigm: Novel Structures and Metabolic Pathways in the Emerging Dairy Species Pseudolactococcus laudensis and Pseudolactococcus raffinolactis".

ABSTRACT: Cell surface-associated polysaccharides, including cell wall polysaccharides (CWPSs), capsular polysaccharides (CPSs), and exopolysaccharides (EPSs), play vital roles in bacterial interactions with their environment, influencing critical aspects of dairy fermentations, such as phage-host dynamics. Pseudolactococcus laudensis and Pseudolactococcus raffinolactis (formerly Lactococcus laudensis and Lactococcus raffinolactis) are emerging dairy-associated species whose CWPSs remain uncharacterized. This study analyzed the complete genomes of 21 P. laudensis and seven P. raffinolactis strains to investigate the genetic diversity underlying CWPS and EPS production. Eight novel cwps genotypes (E-L) were identified, significantly expanding the known diversity within the dairy-associated (pseudo)la
